10 Tips to Not Hate Hot Summer Running

Running in the heat and humidity of the summer can be dangerous, but with these tips, you’ll be training all summer long. 

I don’t know about the weather where you live, but it is freaking HOT in Winston-Salem. HOT & HUMID. I love running outside but with weather like this, it can be downright dangerous. Not to mention miserable. But with a few easy tweaks to your running routine, hot miles can feel a little better. And, maybe, just maybe you’ll grow to like them.

When I’m not focused on my pace (Tip #7!), I am able to appreciate just how much I’m sweating which is oddly satisfying. Although, I do love my summer runs in Utah when I don’t finish my runs completely drenched!! I guess it’s fair to say I just love running, period. 

tips for running in hot weather

Here are a couple common questions I get from readers and followers during the summer months.

Is it bad to run to run in hot weather?

Running in hot weather isn’t bad. But being dumb or lazy about it can be bad. When it’s extra hot out, you sweat more, which can lead to dehydration faster. And dehydration can go very bad very quickly. You need to carry fluids (see tip #1!).

How does heat affect running?

Heat and/or humidity, simply put, make running harder. Both elements tax the body and, combined, they especially tax the body, increasing your heart rate more quickly.

That means your heart is beating harder for the same pace you’d run in cooler temps. And that means your run will feel harder and/or you won’t be able to hit your normal paces. Tommy quickly learned this in February when we visited Palm Beach, Florida!

Here’s everything I employ when running in the summer to stay safe and a little more sane!

10 tips to not hate life running in the heat

1. Carry fluids  

I drink 16 oz of ice cold water with Nuun (for electrolytes) before I run and I carry water on my run, even for distances I normally wouldn’t. In the cooler months, I rarely carry water with me on runs shorter than six miles. But in the heat, I always run with water or Nuun. 

In hot temps, you will dehydrate more quickly and will need to rehydrate along the way. This is the water bottle I carry – the hand strap is key so it’s not super annoying. I keep my water bottle in the fridge so it’s cold when I head out. 

The goal with cold water before and during is to help keep your core temperate low!

2. Be sure you are well fueled

Aside from being hydrated, make sure you’re fueled before you head out. Remember, all runs will feel harder in the heat so you’ll want to make sure you aren’t running on empty.

In the summer, I like a couple dates or a banana with peanut butter. Giddy Up Bites from Run Fast Eat Slow are great too – I keep them in the freezer. Cold food, cold water, happy me.

3. Wear light, wicking clothing

Wear something breathable and sweat-wicking. (I have my favorite tops and shorts listed on this page.) I wear a visor most days to keep the sun off my face (a visor rather than a hat so heat can escape my head).

If I’m going for sunglasses, they’re always Goodr sunglasses since they don’t slip down my face even on my sweatiest days and the price can’t be beat.

And please, for the love of all that is good and wise, don’t wear cotton, especially if you live in a humid environment. It will trap the heat escaping from your body, hold onto your sweat, and make you hotter.

4. Wear suncreen 

After having three friends in their late 20s get melanoma, I take SPF seriously. I apply sunscreen before any run where I’ll be in the sun for any amount of time, even in the morning. I like Beautycounter Mineral Sunscreen. It doesn’t leave that crazy white cast that some zinc-based sunscreens do, it’s sweat proof and safe (for our bodies and for the reef) so it’s a win all around.

5. Plan a shady route, or run in the off hours 

One of the best things you can do is run in the off hours — early in the morning or later in the evening. The sun will be much more intense from 11am-3pm and oftentimes, 5-6pm can be the hottest time of day. If you can get out early in the morning or wait until a little later in the evening, it’ll help a lot.

While I personally run in the mornings with friends, I also really love evening runs. When I was doing two-a-days while training for the Boston Marathon earlier this year, I had my second easy run in the evenings and it quickly became a favorite way to unwind after a long day.

6. Start much slower than normal and expect to run slower throughout your run

In the winter, you start slowly to allow your body extra time to warm up in cold temperatures. And in the summer, you want to start slowly so your body temperature and heart rate don’t spike as early on in your run. That will help your run feel a little better for a little longer.

A good rule of thumb is that your pace will be about 20-30 seconds slower than your “normal” pace. But some days, you may run 90 seconds slower. Or more. It’s ALL OKAY. Just slow down. It’s not a big deal. I promise. If it helps, brag on Strava about how much slower you can run when it’s hot – make that your claim to running fame.

And remember that EVERYONE is slower in the heat. It’s science. It’s not just you. This calculator is handy to see how the conditions will impact you on any given day. And the Dark Sky app will show you what time of day the Dew Point is the lowest. (Side note: It’s one of the few apps I’ve paid for because it’s super handy when planning runs around wind, rain, temps, everything. I find it’s more accurate than the iPhone weather app.)

7. Run by effort & take walk breaks

Run by effort, not your typical pace when it’s hot. If you have an easy day, run a pace that allows you to say complete sentences. If you have a workout, either adjust your interval/tempo pace or run the effort you should be feeling for the particular intervals. Don’t let a training plan override common sense.

And don’t be too uptight or stubborn to take walk breaks. My friends and I walk at least 3-4 times during summer runs. It’s usually only 30-60 seconds but it helps a lot to have a little breather.

If you’re not feeling strong, SLOW DOWN! And if you feel dizzy or lightheaded, STOP IMMEDIATELY.

8. Run with someone — or tell someone your plans

If you can find a running buddy, it really makes the most miserable conditions a bit more tolerable!

If you don’t have anyone to run with, make sure you let someone know when you’re running and when you plan to be back. This is a good habit for all your runs – not just hot ones. I always let my husband know my running plans, including when I’m leaving, roughly how long I plan to run and the general route I’m going.

9. Pour Water ON your body, not just in it

The goal with this is to keep your core body temperature down as much as possible. If you ever watch elite runners during a race, you will likely see this. I pour it on my head and down the back of my neck. It might seem intense or silly, but it seriously helps! Some people swear by putting cold water on their wrists.

I employed this strategy during the 2019 Boston Marathon and it’s part of the reason I felt strong the entire race, even as temps rose.

10. Listen to your body

Bottom line – be smart. Your life doesn’t depend on hitting a certain pace or distance. But it can be life threatening if you don’t pay attention when your body is screaming at you. There will always be another run.

    Catching up on your posts (work has been crazy!), and this one is so fitting right now! Started my 16 miler this morning at 78 degrees with 98% humidity and finished at 84 degrees. It was tough! These tips are great! I’m hoping that training now will make running in Utah in September feel magical! haha

      oh oof! Where did you have 98% humidity? Certainly not in Utah! ha!

      September running in Utah is the BEST.

        Central Texas! There’s no way to escape the heat or humidity during the summer. You get one, the other, or both! 🙂
